    • A thermoforming machine with a moving tilting bed (4), comprising a forming station consisting of a lower mold nest (3) and a fixed upper mold nest; the lower mold nest is supported by a moving bed which has a closure position, in which the molding of the workpieces is performed, and an ejection position for the molded pieces; the bed is movable linearly and is rotatable about its axis. The moving tilting bed is directly controlled by a movement mechanism (8) which causes it to perform the vertical movement, by means of a simple crank/connecting-rod system (9, 10). The rotary/translatory movement of the tilting bed is controlled by two gearmotors (11, 12), with an absolute encoder, which are managed by a PLC program. In the case of anomalous operation of the electronics, namely should there be any displacement between the programmed vertical position and the associated rotation, a mechanical safety device consisting of a cam and cam follower intervenes.
    • 一种具有移动倾斜床(4)的热成型机,包括由下模具座(3)和固定上模具座组成的成形站; 下模具座由移动床支撑,该移动床具有闭合位置,在该位置执行工件的模制,以及用于模制件的喷射位置; 该床可线性移动并且可围绕其轴线旋转。 移动的倾斜床由通过简单的曲柄/连杆系统(9,10)进行垂直运动的运动机构(8)直接控制。 倾斜床的旋转/平移运动由两个减速电机(11,12)控制,绝对编码器由PLC程序管理。 在电子设备出现异常操作的情况下,即在编程的垂直位置和相关的旋转之间应有任何位移,由凸轮和凸轮从动件组成的机械安全装置进行干预。
